4.

 

Check whether the system voltage has been manually set to a very low value. If so, 
check with other maintenance personnel whether the voltage can be changed to a normal 
value. 

5.

 

Check whether faulty rectifiers have resulted in insufficient power system capacity for 
the loads. If so, replace the faulty rectifiers. 

4.2.6 Batt Chg. Overcur. 

Possible Causes 

 

Rectifier communication is interrupted. 

 

SMU connections are loose. 

 

The SMU is faulty. 

Measures 

1.

 

Check whether an alarm has been generated for interrupted rectifier communication. If 
so, remove the rectifier, reinstall it, and check whether the alarm is cleared. If the alarm 
still exists, replace the rectifier. 

2.

 

Remove the SMU, reinstall it, and check whether the alarm is cleared. If the alarm still 
exists, replace the SMU. 

4.2.7 LLVD Disconnected 

Possible Causes 

 

An AC power failure has occurred. 

 

Loads are manually disconnected. 

 

The load disconnection voltage has been set to a very high value on the SMU. 

Measures 

1.

 

Check whether an AC power failure has occurred. If so, rectify the fault to restore the 
AC power supply. 

2.

 

Check whether loads are manually disconnected. If so, check with other maintenance 
personnel whether the loads can be reconnected. 

3.

 

Check whether the load disconnection voltage (44 V DC by default) has been set to a 
very high value on the SMU. If so, adjust it to a normal value. 

4.2.8 BLVD Disconnected 

Possible Causes 

 

An AC power failure has occurred. 

 

Batteries are manually disconnected. 

 

The battery disconnection voltage has been set to a very high value on the SMU. 

Measures 

1.

 

Check whether an AC power failure has occurred. If so, rectify the fault to restore the 
AC power supply.
